Effects of Parent Coal Properties on the Pyrolytic Char Chemical Structure: Insights from Micro-Raman Spectroscopy Based on 32 Kinds of Chinese Coals
Round 1
Reviewer 1 Report
An interesting and well-prepared paper.
I have some doubts about the validity of the results. Because it seems to me that the correlations presented are not strong enough. Therefore, the comprehensive coal property index may be misleading. Possibly, a number of other factors affect the chemical structure of the chars.
However, I find interesting the correlation idea of parent coal-properties and chemical structure of the chars.
Correct "funcation" in Fig 9.
It would be better if the correlation figures are normalized.
Add a short phrase to the conclusions for future research recommendation
